FANNING-NIILL.

SPECIFICATION forming part of Letters Patent No. 375,524, dated December27, 1887.

Application filed February l, i886. Serial No. 180,445. (No model.)

To all whom, it may concern.:

Be it known that I, OHRIsTorHER ALT- RINGER, of. Racine, in the countyof Racine, and in the State of Wisconsin, have invented certain new anduseful Improvements in Fanning-Mills; and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention relates to fanning-mills and separators; and it consists incertain peculiari-- ties of construction, as will be fully set forth vand claimed hereinafter.

In the drawings, Figure l is a perspective view of a-fanning-millembodying myimprovements. Fig'. 2 is a vertical longitudinal sectionofthe shoe thereof. Fig.3 isa plan View of part of the same,illustrating a modified construction; and Fig. 4 is a detail sectionalview of the hurdle on the line w m of Fig. 2.

My present invention is in part an improvement on the machine patentedto me and to Nicolaus Altringer and Nicolaus Altringer, Jr., on July 26,188i, and numbered 244,727.

A represents the fanning-mill frame and case.

B is the shoe.

C is a hurdle of sieves.

D D are screensbelow the hurdle,inclining up toward the same at the rearofthe machine, the said hurdle inclining downward at that point, asshown.

The fannin'g-mill proper and the shoe are about the same as in the priorpatent named; but the hurdle C in the present case is of a differentconstruction. It consists of two screens or sieves, c and c', suitablyunited at their sides by the side bars, c3 c3, above which are otherside strips, c4 0*, while resting on and secured to the upper surface ofthe rear edge of the lower sieve, o', is a block, c2,whose upper surfaceis normally just under the lower surface of the rear edge of the uppersieve, c, but without being in contact therewith, all as clearly shownin Fig. 4. Across the top of the hurdle C are two strengthening-bars,e505, secured to the described strips c4 @tand in the preferred form ofmy present device (illustrated in Figs. l, 2, and 4) I pivot two shortstrips or bearings, ci c, between the strengthching-bars c5 c5, and tothese strips c, I secure the ends of the pounding bars or levers EE',

(of which I employ two in my present invention in place of the singlepounding-bar shown in the patent hereinbefore referred to;) or,ifpreferred, I may omit the bearingstrips cG and simply hinge or pivot theends of the pounding-bars E E' to the sides of the shoe, as shown at c7clin Fig. 3. To the strips c6 (or, ifthe form of device shown in Fig. 3is used,directly to the levers E E') I secure vertical eyebolts e2 e2,from which there extend cords e3 c3,the other ends of which pass throughholes in the upper rear extensions, a a, of the farming-mill above theshoe,which cords,after proper adjustment, are secured therein by meansof the pins a a'.

The upper screen, D, has attached to the under side of its rear part thestrip F by means ofa bolt, d, passing through a slot, j', in the saidstrip F, whereby whenv the bolt d is loosenedthe strip can be adjustedso as to project a greater or'less distance from the rear end of saidscreen, as desired, and secured in the preferred position byretightening the bolt. The extreme outer or rear end of the strip Fcarries on its upper surface ablock, f', and on its under surface, aslight distance from said rear end, another block, f2, the latter blockbeing designed to normally be just above, but without touching, the rearedge of the lower screen, D.

Fower is communicated to the mill in the ordinary manner and transmittedthrough the gearing shown, Gg, to the main shaft a2 of the fan, and bymeans of the cranlr-pin, )itman b, and elbow-lever b', shoe-hook b2, andconnections to the shoe B, substantially as in my prior patent, No.126,371, granted to me May 7, 1872. These parts serve to give the shoe Bthe desired side motion, and at the same time, as the shoe thusreciprocates, the cords e3 e3 are alternately drawn taut, thereby inturn raising the pounding bars or levers E E', while as one cord istightened the other is relaxed, permitting the lever to which it isattached to fall. In the arrangement shown the head e of the lever Estrikes upon the upper rear edge of the sieve c of the hurdle C andvibrates that sieve and depresses it upon the block c2, attached to thesieve c of the hurdle, and thereby vibrates the latter sieve also, whilethe head e of the lever E in its turn strikes upon the IOO block f ofthestrip F, attached to the screen D, and thus vibratcs it, at the sainetime de pressing said strip F, so that its other block, f, strikes theedge of the lower screen, D, and thereby transmits the vibration tothatsereen also. Of course, in place of the doublesieve hurdle, a singlescreen may be substituted; but the arrangement shown is very effective,notably for flax and similar small seeds. In some instances I may omitthe block f and make the head e of the lever Elong enough to strike theend of the strip F; but ordinarily I prefer to use the block, as stated.

If desired, my hurdle might have three or more sieves,the additionallower sieve or sieves belng like the lower sieve of the hurdle shown 1nFig. 4, (with similar blocks, c2, to transmit vibrations,) and similarlythe number of screens used is immaterial; butin most cases a p air ofscreens, as shown, will be found sufficient.

Having thus described my invention, what l claim as new, and desire tosecure by Letters Patent, iS-

l. rlhecombinationof the frame, avibrating shoe carrying sieves orhurdles, and a pair ol' pounding bars or levers attached to the saidvibrating shoe and flexibly connected to fixed parts of the frame atopposite sides thereof above the shoe, whereby the said poundingbarswill be alternately raised and let fall by the vibrating action of theshoe, substantially as set forth.

2. The combination of the frame, a vibrating Shoe carrying sievcs orhurdles inclined downward, and screens inclined upward at theirrespective rear edges, the said lower screens having arearwardly-projecting frame, with a pair ot' pounding bars or leversattached tothe said shoe above the upper sieve, and means whereby theyare flexibly connected to a fixed part of the frame above the slice andadapted to be raised and let fall by the vibrations of the latter, oneof said pounding-bars extending rearwardly farther than the other,wherebythe head of one bar strikes upon the frame of the upper sieve orhurdle, while the head of the other bar strikes upon the projectingframe of the lower screens, substantially as set forth.

3. The combination of the frame and a vibrating shoe carrying sieves orhurdles and lower screens, with a pounding-bar attached to the shoeabove the upper sieve and proj octin g back beyond its rear edge, meanswhereby the bar is flexibly connected with the frame, and an adjustablestrip or frame projecting from the rear edge of a lower screen andadapted to receive a blow from said poundingbar, substantially as setforth.

fi. The combination of a frame, a vibrating shoe having a hurdleconsisting of two sieves connected at their side edges and a blocksecured to the rear edge of the lower sieve of said hurdle, apounding-bar attached to the said vibrating shoe above the upper sieveof the hurdle, and means whereby it is caused to strike thereon, wherebya blow on the said upper sieve will force its rear edge down upon thedescribed block, and thereby vibrate the lower sieve of the said hurdle,substantially as set forth.

5. lhe combination of a vibrating shoe carrying sieves or hurdles andscreens, a pounding-bar attached to the said vibrating shoe above theupper sieve and projecting back beyond its rear edge, means foroperating said bar, a pair of screens below the sieves or hnr- (iles, anadjustable strip or frame projecting from the rear edge of the upperscreen, and a block secured on the under side of said screen over therear edge of the lower screen, whereby a blow from the poundingbar willbe transmitted to the lower screen, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of \Viscon sin, in thepresence of two witnesses.
